If you're working with large source files, you might want to do each piece of work in an independent context with the information discarded afterwards?

Is the context a sliding window, or are there tiers of importance?

By this I mean treat features as isolated plugins. I get that there are cross-cutting features that touch multiple pieces of functionality, and those probably need special treatment, but a large class of functionality can be developed in an isolated way with a common set of design tokens and APIs to tie them all together.

This might play better to coding agent strengths.

Full disclosure: this is very much an armchair view. I have all of 2 weeks of experience coding via agents (vs manually), but this thread is nerd sniping me into trying it myself.
